Experiment Two (2) Torsional testing of Circular Shafts
Experiment Two (2). Torsional testing of Circular Shafts Introduction: Torsion occurs when any shaft is subjected to a torque. This is true whether the shaft is rotating (such as drive Shafts on engines, motors and turbines) or stationary (such as with a bolt or screw). The torque makes the shaft twist and one end rotates relative to the other inducing shear stress on any cross section. Failure might occur due to shear alone or because the shear is accompanied by stretching or bending. Objective: To determine Shear Modulus of Elasticity (G) of some steel , Aluminum and Brass Circular Shafts and develop a relationship among the Torque (T0 and Clamping length (L) and the angle of twist ( ).)
Determination of Modulus of Rigidity, Shear Modulus G and Torsional Stress for Steel and Aluminum. A. Using the reading of above to calculate the shear modulus and torsional stress for Steel, Aluminum and Brass, by using the following formulas. Compare the experimental results with theoretical values. Θ = [180*T*L/(π*J*G)] (eq. 1) τ= T*C/J ...
